OM3212 08/11 Operator Cab and Controls - Section 32 Page 32-33 Transmission Response With Fault Codes When the transmission controller detects any of the severe fault that are listed below while the engine is running, the transmission will shift to the neutral gear position. If the truck needs to be moved with one of these fault codes present, the following procedure is suggested: 1. Bring the truck to a stop in a safe location. Apply the parking brake and move the range selector to the NEUTRAL position. 2. Next, move the range selector to either DRIVE, 5th, 4th, 3rd, LOW or REVERSE.
With one of the previously listed failure codes the transmission will fail to NEUTRAL, in order to move the truck the following procedure should be followed. The transmission will then shift to F1, F2, or F3 when either of the forward positions was selected, DRIVE, 5th, 4th, 3rd, LOW or REVERSE when the R position was attained. 3. The selection of F1, F2, or F3 will be dependent on the type of fault. 1. Bring the truck to a stop in a safe location. Apply the parking brake and move the range selector lever to the NEUTRAL position. 2. Next move the range selector to either Drive, 5th, 4th, 3rd, LOW or REVERSE.
The transmis- sion will then shift to F1 or F2 when either of the forward positions was selected; DRIVE, 5th, 4th, 3rd, LOW or REVERSE when the R posi- tion was attained. If any of the severe fault codes that are listed in the table below appear on the warning screen, perform Steps 1-5 (listed below the table). 3. The selection of F1 or F2 will be dependent on the type of fault. If the transmission controller detects any of the following severe fault codes with the engine running, the transmission will remain in the gear that it was in at the time of the fault code. When the range selector is moved to the N position the transmission will shift to the N range also.
